Pico CMTS

We are having all sorts of problems with MTA's. We use only Arris eMTA's. Currently on Pico's latest software (v3.85/v352) and the eMTA no longer gets an IP address. They received an IP once at 11pm Saturday night, yet that went away sometime Sunday morning. Pico's support has been virtually non-existant on this. We use Promptlink's IPS for provisioning. The Arris CM's get an IP just fine and the CPE's receive IP's just fine, it is just the eMTA's that do not get IP addresses. Below is the log from Promptlink showing the DHCP offer is sent and attached is the Arris MTA DHCP log showing nothing received.

i don't have familiarity with PICO cmts'es but what your describing sounds like a different issue.

Arris mtas will ignore dhcp offers that come from ips that are not listed in option 122.1 in the cable modem dhcp offer.

So what I would check is that the ip (or the ip that is resolved if using dns) that you have specified as provisioning server I think it is option 122.1 is the IP that the MTA is receiving the offer from. If they are not the same, the Arris mta will silently ignore dhcp offers. (unless you are looking at debug input)

You can check both of these using the advanced web page and the password of the day.
